Origin
The surname Crumpacker has its origins in Germany, where it is believed to have emerged in the 16th century. The name is thought to derive from the Middle High German word "krumpfe," meaning "bent" or "crooked," and the suffix "-bacher," indicating someone who lived near a crooked stream or brook.
Historical records trace the earliest instances of the Crumpacker name to the German state of Hesse, particularly in the towns of Hersfeld and Frankenberg. In the late 16th century, a document from the town of Hersfeld mentions a certain Johann Crumpacker, who was a baker by trade.
As the name spread throughout Germany, variations in spelling emerged, including Krumpacker, Krummbacher, and Krumbacher. These variations reflect the regional dialects and the inconsistencies in record-keeping during that era.
One notable historical figure bearing the Crumpacker surname was Johann Michael Crumpacker (1683-1758), a Lutheran minister and theologian from Alsfeld, Hesse. He authored several religious treatises and was highly regarded in his time.
The Crumpacker name eventually made its way to other parts of Europe, including Switzerland and France, where it underwent further linguistic adaptations. For instance, in the Swiss canton of Bern, the name appeared as Krummbacher.
In the late 17th and early 18th centuries, several Crumpacker families immigrated to the American colonies, primarily settling in Pennsylvania and Virginia. One of the earliest recorded instances is that of Jacob Crumpacker, who arrived in Philadelphia in 1727 from the Palatinate region of Germany.
Another notable figure was John Crumpacker (1738-1817), a soldier and pioneer who fought in the American Revolutionary War and later helped establish settlements in western Virginia (now West Virginia).
Throughout the 19th century, the Crumpacker name gained prominence in various fields. For example, Edgar D. Crumpacker (1851-1923) was a U.S. Congressman from Indiana, while Jacob S. Crumpacker (1837-1920) was a successful businessman and philanthropist in Virginia.
While the Crumpacker surname has evolved over centuries and spread across continents, its roots can be traced back to the German regions of Hesse and the Palatinate, where it originated as a descriptive name for those living near crooked streams or brooks.
Demographics
Among Census respondents with the surname Crumpacker, the largest self-reported group is White at 94.8%. The next largest groups are Two or More Races (3.6%) and Hispanic (1.1%).
The bar chart below shows how Crumpacker bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Crumpacker surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
